The attack happened about 8 a.m. in the Belair Subdivision near Slidell.

Investigators said the woman was walking her miniature collie on the walking trail near Hunters Point Road when two dogs, described by the Sheriff's Office as pit bulls, approached her and began attacking the woman's dog. When the woman attempted to stop the dogs, they attacked her.

A neighbor heard the woman screaming for help and came to her side and shot his 9mm pistol at them, killing one of the dogs and injuring the other, investigators said.

Deputies found the owner of the dogs, 22-year-old Leonard Harvey of Slidell, and issued him a misdemeanor summons for violating the parish leash law.

St. Tammany Parish Animal Services took custody of the injured pit bull and the body of the dead dog.

The injured dog was euthanized at Harvey's request, authorities said, due to the extent of the injuries and fear that his dog would attack again.

The woman was taken to the hospital to be treated for bite wounds to her left arm and left leg. Her dog was taken to a local veterinary clinic to be treated for injuries.
